The MAX6968AAE+T is a Programmable Column/Row LED Drivers from Maxim Integrated, which are specially designed for use in backlighting portable devices such as mobile phones, media players, and PDAs. This device is intended to drive up to 8 columns and 8 rows of Control of LEDs individually or in groups. The drivers support various operating modes to help reduce the power consumption and extend the battery life. This driver also supports brightness control and various dimming modes such as PWM, analog source current, and digital slew rate.

The MAX6968AAE+T is a highly integrated device with 16 high-current outputs capable of delivering a maximum of 40mA each. Its small size makes it suitable for space-constrained designs while its low power consumption and high power output make it an ideal choice for applications with tight power budgets. Additionally, this driver features open-drain outputs with adjustable fall times for smooth dimming and an internal power-on reset. The MAX6968AAE+T enables easy integration into existing designs with its low operating voltage range of 1.8V to 5.5V.

The MAX6968AAE+T features unique column/row segment/digit control, allowing for higher brightness as this part can be completely dimmed or completely turned-on. In addition, the LED current for each LED can be programmed independently using the internal registers. This driver also offers an adjustable increment/decrement count rate and start/stop control, allowing for blinking and fading effects programming.

The MAX6968AAE+T also supports a dedicated test-mode pin, which allows for easy debugging and testing of the LED array. The device is designed to function with a wide variety of LEDs, including white, red, green, blue, yellow, or combinations of any of these colors. As a result, this device is widely applicable as an LED driver to provide efficient and robust lighting solutions for various display backlighting applications.

In summary, the MAX6968AAE+T is an ideal choice for portable device backlighting. Its small size, highly integrated features, and adjustable current capability are ideal for batteries and space-constrained applications. Its adjustable current control and unique column/row segment/digit module make it suitable for applications requiring robust and efficient lighting solutions. Additionally, its programmable open-drain outputs provide smooth dimming for high-precision brightness control. This device’s low operating voltage range, wide compatibility, and large range of features make it an ideal choice for mobile device backlighting.
